The MLX 90614 sensor is an IR sensor used to measure temperature without contact. This sensor can measure the object's temperature and ambient temperature in the range of -40 oC – 125 oC. These sensors are widely used in areas such as room temperature measurement, machine temperature, ambient temperature, and body temperature. The MLX 90614 sensor is not yet fully usable directly to perform temperature measurements due to the program's simple defaults so that the measurement results are inaccurate. Therefore, optimization is needed to increase the precision value of the body's internal temperature estimation using this sensor. The method carried out in this study used 6 experimental sheep. Temperature checks are performed through a contact thermometer and compared to non-contact checks by MLX 90614 sensors. Results showed the average temperature of the contact thermometer was 39.28±0.09 oC while the MLX sensor yield was 35.78±1.38 oC. The average temperature difference was 3.5±1.48 oC. The results showed that the temperature difference correction factor needs to be included in the script code when running MLX 90614 sensor. The results of temperature checks by the sensor can be sent directly in real time to the ThingSpeak platform so that the results can be stored and accessed in different places easily. The use of MLX 90614 sensor combined with IoT concept using ThingSpeak can facilitate the process of non-contact body temperature check, and also make the data can be accessed dan stored easily.

Body Heat

During the COVID-19 pandemic, the price of preventive equipment such as masks and hand sanitizers has increased significantly. Likewise, thermometers are experiencing an increase and scarcity, this tool is also sought after by many companies for screening employees and guests before entering the building to detect body temperatures that are suspected of being positive for COVID-19. The use of a thermometer operated by humans is very risky because dealing directly with people who could be ODP (People Under Monitoring/Suscpected ) or even positive for COVID-19, therefore we need tools for automatic body temperature screening and do not involve humans for the examination. This research uses the MLX-90614 body temperature sensor equipped with an ultrasonic support sensor to detect movement and measure the distance between the forehead and the temperature sensor so that the body heat measurement works optimally, and a 16x2 LCD to display the temperature measurement results. If the measured body temperature is more than 37.5 ° C degrees Celsius then the buzzer will turn on and the selenoid door lock will not open and will send a notification to the Telegram messaging application. The final result obtained is the formation of a prototype device for measuring body temperature automatically without the need to involve humans in measuring body temperature to control people who want to enter the building so as to reduce the risk of COVID-19 transmission

Thermocouple Material

Peltier modules or Peltier tiles utilize the Seebeck phenomenon, where a semi-conductor thermocouple material is flanked by 2 plates, if one side is hot and the other side is cold, the module will produce a voltage whose value is proportional to the temperature difference. This effect can be applied in reverse. If the module is electrified, it will produce heat on one side and cold on the other side. Jacket as a heater is applied when the ambient temperature is lower than the body temperature. The temperature of the heating jacket is 53.1 ℃. In the experiment 6000 mAh battery can provide power for Peltier for 35 minutes.

The outbreak of the novel coronavirus pneumonia has had a great impact on the life safety of our people and social production activities. Therefore, it is very important and meaningful to analyze the application value of infrared forehead thermometers in body temperature screening under the new crown pneumonia epidemic and propose improved measures for body temperature detection. This paper summarizes the questionnaire on the application value of infrared forehead thermometer in body temperature screening and the results of staff interviews, and analyzes the principle of infrared forehead thermometer temperature measurement to explain the factors that affect the accuracy of temperature measurement results. Finally, it is concluded that the reflected radiation of the environment and the temperature measurement distance affect the accuracy of the temperature measurement results of the infrared forehead gun.

The Impact

To achieve a sensitive and accurate method in body temperature measurement of cattle, this study explores the uses of infrared thermography (IRT), an anemometer, and a humiture meter as a multiple sensors architecture. The influence of environmental factors on IRT, such as wind speed, ambient temperature, and humidity, was considered. The proposed signal processes removed the IRT frames affected by air flow, and also eliminated the IRT frames affected by random body movement of cattle using the frame difference method. In addition, the proposed calibration method reduced the impact of ambient temperature and humidity on IRT results, thereby increasing the accuracy of IRT temperature. The difference of mean value and standard deviation value between recorded rectal reference temperature and IRT temperature were 0.04 °C and 0.10 °C, respectively, and the proposed system substantially improved the measurement consistency of the IRT temperature and reference on cattle body temperature. Moreover, with a relatively small IRT image sensor, the combination of multiple sensors architecture and proper data processing still achieved good temperature accuracy. The result of the root-mean-square error (RMSE) was 0.74 °C, which is quite close to the accurate result of the IRT measurement.

Polycrystalline Molybdenum

The evolution of dislocation channels in irradiated metals during deformation can be envisaged to occur in three stages: (i) formation of embryonic cluster free regions, (ii) growth of these regions into microscopically observable channels and (iii) termination of their growth due to the accumulation of dislocation damage. The first two stages are particularly intriguing, and we have attempted to follow the early stages of channel formation in polycrystalline molybdenum, irradiated to 5×1019 n. cm−2 (E > 1 Mev) at the reactor ambient temperature (∼ 60°C), using transmission electron microscopy. The irradiated samples were strained, at room temperature, up to the macroscopic yield point.Figure 1 illustrates the early stages of channel formation. The observations suggest that the cluster free regions, such as A, B and C, form in isolated packets, which could subsequently link-up to evolve a channel.

Progressive Decrease

The effects, on the body temperature of white mice, of repeated short exposures to cold were investigated using two methods of restraint. Animals held in a flattened posture became hypothermic at room temperature, cooled more than five times as fast at −10 °C as mice that could adopt a heat-conserving posture, and continued to cool for some time after they were removed from the cold. With repeated tests, cooling at room temperature decreased, and an improvement in re warming ability was observed. In addition, with lightly restrained mice, the fall in rectal temperature during cold exposure showed a progressive decrease, a phenomenon not observed with severely restrained animals.
